Components Supplied• Bulletin 48MS MultiSight vision sensor with integrated lighting• Computer software on CD-ROM• Installation instructions, mounting bracket 48MS-BKTDT with three screws, Allen wrench, screwdriver, and protective cap for

M12 Ethernet connector.• Two PVC M12 QD covers (must be installed around the metal coupling nuts of both connection cables for ESD protection).

Typical ApplicationsThe MultiSight is an optical multipixel sensor with a pass/fail PNP output. The MultiSight uses three ( four) different methods of evaluation (pattern matching, contrast, brightness, and contour matching) to detect or differentiate objects by means of previously defined optical characteristics, e.g. for separating “good” and “bad” parts. The main applications are in the field of industrial automation for quality assurance purposes. The MultiSight can be used for detecting presence or absence, completeness, position, markings, labeling, packaging, and components. The MultiSight is an economical alternative to conventional vision systems.

Requirements for UseTo configure the MultiSight, the following items are required: PC or notebook with minimum Pentium III, 1 GHz, 256 MB RAM, Microsoft Windows 98, 2000, XP™, or Vista™ network connection or network with TCP-IP protocol. Recommended screen resolution 1024 x 768 pixels. Basic knowledge of computing and electronics wiring is also essential. The IP address of the MultiSight is set by the manufacturer to 192.168.100.100 with sub-net mask 255.255.255.0.

The operation of the MultiSight is independent of a computer or PLC. A PC or notebook is required only for configuring the sensor.

For reproducible results and avoidance of malfunctions, adequate and consistent object illumination is essential.

Reflections or varying incident light may affect detection results.

If necessary, use an external white-light source and/or light-screening devices to exclude incident light.

Description of Operation

BasicsThe image recorder of the MultiSight is a CCD chip with a resolution of 640 x 480 pixels. Evaluation is based on 320 x 240 scanning points. The sensor is designed for inspection and cannot provide measurement information. To operate the MultiSight, at least one virtual detector must be configured by designating a Region of Interest and teaching a sample image (see screen shot on page 20). This virtual detector is stored in a non-volatile flash memory on the sensor and is re-activated for standalone operation after switching off and on. Standalone operation is, therefore, possible with or without PC or PLC.

Evaluation MethodDuring operation, the MultiSight continuously compares the pattern of the detected image with that of the reference image. The pixel grey-scale values of the sample are analyzed and a level of conformity to the original sample is determined. If this level falls within the user adjustable threshold settings, the sensor turns the PNP output ON or OFF (i.e., the part passes or fails the inspection).

The EtherNet/IP connection is capable of communicating additional data about the inspection.

Setup

Installation Instructions

InstallationTo help provide maximum accuracy of detection, the MultiSight should be protected from vibration.

Attach the MultiSight onto the dovetail mounting bracket, 48MS-BKTDT (supplied with the unit) and then onto a suitable object above the target. Use only the 48MS-BKTDT for mounting the unit (see “Approximate Dimensions—mm (in.)” on page 68).

The PC must be connected to a MultiSight sensor via the Ethernet port to load the configuration software. Also, Run mode of the sensor is automatically stopped when the software connects to the sensor. The software is tightly integrated with the firmware on the sensor. As parameters are changed in the software they are changed in the sensor. There is not a typical “download” or “upload” process, but the “write to flash memory” button in the software must be pushed to save the settings from the sensor’s RAM to the sensor’s nonvolatile flash memory. The Teach command is used only for teaching the pattern, contour, or shutter speed (in automatic shutter adjustment mode). The active detector in the software is the active detector in the sensor. This means that if the sensor is switched to run mode, whatever detector was most recently selected in the software will determine the output of the sensor ( unless it is changed via EtherNet/IP).

If an EtherNet/IP connection is established, the Logix add-on profile output tag FirstDetector will control which detector is active and override the configuration software setting. To give control of which detector is active back to the configuration software, set the FirstDetector tag value to -1.

Secure the connection cables with cable binders to prevent crushing or slipping.

Select a position for the MultiSight in which interfering factors such as slight differences in the position of the object or variations in lighting have little or no effect.

Fine Adjustment

Electrical Installation

Fine adjustment of the MultiSight should not be carried out until after electrical connection and start-up (PC software installation) (see “Start-up” on page 18).

The electrical installation of the MultiSight must be carried out by a qualified electrician.

When installing the MultiSight disconnect all electrical components from the power supply.

When the unit is used on a network, make sure that the network address (IP address) of the MultiSight set by the manufacturer at 192.168.100.100 is still free and is not in use by any other unit connected to the system.

If necessary, reset the IP address of the MultiSight as described in “Network Settings” on page 11.

When the MultiSight is in use, the protective caps supplied must be covering the M12 socket (Ethernet) if it is not in use. Failure to do this may cause malfunction.

EtherNet/IP models only:The supplied black PVC M12 covers must be installed around the coupling nut of each connection cable (Power-I/O and ethernet) to protect from ESD when using standard cables. (There is a plastic nut on the MultiSight specific cables to provide this ESD protection, so the PVC cover is not required for 48MS-CS-2 and 48MS-ECSCROSS-3.)

Basic Settings for PC and MultiSightTo configure the MultiSight Sensor with a PC it is essential that Ethernet capability is installed in the PC and the LAN connection on the PC is active with a TCP/IP protocol. This also applies when the PC is not connected to a network (see “Network Connection” on page 8). In addition, every machine in the network must be allocated a unique IP address.

The IP address consists of four decimal blocks in the format aaa.bbb.ccc.ddd where each block may have a value from 0-255. The first three decimal blocks (aaa.bbb.ccc) form the address area.

In order to use the configuration software, the address area of the PC and the MultiSight must be identical. The fourth decimal block (ddd) must be different.

The sensor finder tool (Connect/Find) can be used to change the IP address of the MultiSight, even if the address area of the PC and MultiSight are different.

Example:

If the IP address of the PC is 192.168.2.67, any address between 192.168.2.1 and 192.168.2.254 can be selected for (with selected subnet mask 255.255.255.0) the MultiSight, with the exception of the IP address of the PC (192.168.2.67) and the IP addresses of any other machines in the network.

The IP address of the MultiSight is set by the manufacturer to 192.168.100.100. In the above example, the IP address of the MultiSight therefore has to be reset to the address range of the PC (see “Setting the IP Address of the MultiSight” on page 15).

Setting the IP Address of the PC

The IP address of the computer needs to be set when the MultiSight is directly connected with the computer (see “Electrical Installation” on page 8) and only if the computer has no IP address. In all other cases, the IP address of the MultiSight has to be adjusted to that of the computer (see “Electrical Installation” on page 8).

For the MultiSight Sensor Finder software to detect a MultiSight via Ethernet, all wireless Ethernet connections from the PC must be disabled. Also, deselect “Check Point SecuRemote” in the Local Area Connection Properties and disable any firewalls.

Contact your system administrator to determine which IP addresses are allowed in your network or locally in your PC, and to carry out the necessary settings on your PC.

2. Click on the “Find” button. After a few seconds, a list of sensors in the network appears. If this does not happen, repeat the Find process.

3. Select the desired sensor by clicking on it.

4. Click on the “Set IP” button and enter the desired IP address for the MultiSight (same as the IP address of the PC except for the last block, see “Basic Settings for PC and MultiSight” on page 12). Click Set to accept.

It is possible to adjust the subnet mask and standard gateway using the set IP function. It is recommended to not change these settings unless necessary.

5. Switch the power to MultiSight off and on again, and click on Find again to locate the sensor with the newly assigned address.

Note: the period between the sensor re-start and successful Find is approx. 6 sec. If necessary, repeat Find operation.

The MultiSight is now ready for operation at the newly-assigned IP address.

For network operation use only IP addresses which have not already been assigned.

Contact the system administrator to determine which IP addresses are allowed on your network for the MultiSight. The IP address set for the MultiSight should be marked on the enclosed label. After installation, stick the label on the sensor in a clearly visible position.

It is not possible to see a MultiSight on a different standard gateway than your PC using the sensor finder function.

26 10000000877(02)

Select Detector

The MultiSight can be configured with up to ten ( 32) virtual detectors (i.e. inspection of ten ( 32) different characteristics). In order to configure one of the ten ( 32) detectors, select the appropriate numbered radio button in the Select Detector window. The current configuration of that detector appears and can be edited in the Detector Parameters section. (If that detector on the MultiSight has not been previously configured, the default values appear.) Parameters that are changed in the software are immediately changed on the MultiSight in dynamic memory. In order to permanently save changes in Flash memory on the MultiSight, click the Write to Flash button in commands window..

When the sensor is in run mode, each detector is independently evaluated. The results of these evaluations are indicated to the right of the radio buttons for each detector. The small grey dots change color to represent the results of the individual detector evaluation, with green indicating PASS and red indicating FAIL. The first dot is for inspection (pass/fail) OUT1 (LED Q1) and the second dot is for position OUT2 (LED Q2). While in run mode, a green (or blue) line on the bar graph indicates the degree of similarity to the pattern or contour the sensor has been taught for that detector. When using contrast or brightness detector types, the bar graph indicates the level of contrast or brightness. The black line on the bar graph represents the threshold (configured in the “Detector Parameters” on page 34).

Detectors can be logically linked together. For example, the sensor can be set up to inspect multiple components on a product. Each component is inspected by a single detector. The evaluation result of each detector is then logically combined with the evaluation results of all the other detectors, resulting in a single output (OUT1/LED Q1). If the AND (All) logic is selected, all selected detectors must pass evaluation for the pass/fail output OUT1 to give a PASS output. (If any one detector fails its evaluation output OUT1 gives a FAIL output.) If the OR (Search) logic is selected, OUT1 gives a PASS output if any one of the detectors passes its evaluation. See the parameter descriptions below for an explanation of how to logically link detectors.

Detectors can also be grouped. The grouping of detectors makes it possible to check several characteristics on different parts without reconnecting the software during part changes. For example, during the first production shift of the day Part A is inspected for several characteristics, then during the second production shift Part B is inspected for different characteristics. The sensor can be changed via the Control Input on the PWR and I/O connector from Part A to Part B without having to reconnect to the software via the Ethernet port. See “Use of Control Input IN2” section on page 58.

Command Description

Recorder Images Transfers the images saved on the MultiSight to the computer.

The MultiSight can save up to 30 images on its local memory. To save images, the Recorder parameter in the Select Detector window must be turned on (see page 27). Based on the setting of that parameter, the MultiSight can save either the last 30 images or the last 30 images of inspections that resulted in an output of FAIL.

When the images are transferred to the computer, they are deleted from the MultiSight memory. In order to keep the image, it must be saved to the computer using the Save button on the Saved Pics pop-up window that opens when the images are transferred.

It is possible to save either the current image or all the images by using the Save or Save All buttons. The images are stored as bitmap files (.bmp).

Images are saved in dynamic memory and are, therefore, lost if the sensor loses power or is turned off.

Logic The Logic field allows the user to define how the detectors are linked together to determine the single OUT1 (pass/fail) output. A detector can be standalone (inspection of a single characteristic), logically linked (multiple inspections on a single part), or grouped (multiple inspections on different parts). (The concept is more thoroughly described in the above general description of the Select Detector window.) The state of the inspection output OUT1 (passes/fails)/LED Q1 is determined by how the individual detector evaluation results are linked in the Logic field.

The evaluation of logically linked detectors is based on a single image. This means that certain detector parameters must be the same for all detectors that are logically linked together (see the chart below). The recommended procedure is to set the first detector in the group to the desired settings, then use the Copy command in the Commands window (on the left of the software screen, see page 24) to copy the configuration of that detector to the other detectors that will be logically linked.

The software will give the error message “group parameter check failed” when the sensor is put into run mode if detectors that are linked together have nonmatching parameters that should match.

The Logic field has the following options:None—No logical link or grouping, i.e. only the selected detector determines the output.AND (All) and OR (Search)—The inspection output OUT1 (pass/fail) is based on the evaluation of all detectors selected via the left-hand check box. (In the screen shot, detectors 1-6 are logically linked.)AND (All)—OUT1 is active if ALL selected detectors pass evaluationOR (Search)—OUT1 is active if ANY of the selected detectors passes evaluation

AND and OR (group)—The group functionality allows the MultiSight to make several different inspections on multiple parts without reconnecting to the software to change between the parts. (This functionality is described more thoroughly above in the general description of the Select Detector window.)

E


30 10000000877(02)


Logic (continued) In order to use the grouping functionality, Detector Parameter Control Input must be set to “Activate 031” for ALL active detectors.

The same Logic is applied to each Group of detectors. Example: if the detectors in Group A are logically linked with AND, the detectors in Group B will be logically linked with AND. It is not possible to link Group A with AND and Group B with OR.

It is not possible to logically link groups with one another.

The functionality of the left-hand check box is different for grouping than for the logical linking previously described. The evaluation of a group begins with the detector last selected via the Control Input (IN2). (When the sensor is connected to the computer for configuration, the radio button currently selected will determine which detector the sensor begins the group evaluation with.) The sensor evaluates each detector that has a check in the left hand box. The next detector that does NOT have a check is the last detector in the group. If detectors 1-3 have a check and 4 does not, Group A is detectors 1-4. See the screen shot to the right.

The detectors in different groups do not have to have matching parameters; however, those within the same group must follow the matching parameter guidelines listed above.

Setting the Threshold Max below the Threshold Min is not possible.

Threshold Min. and Max. (cont.)

In practice, “Good” parts are not 100% identical with the pattern taught. Slight differences in position or fluctuations in light level mean that they do not conform completely to the reference pattern. “Bad” parts should differ from “Good” parts in as many characteristics or as large a part of the pattern area as possible. If a pattern has been taught using a “Good” part, it must first be established what degree of conformity with the pattern is achieved with various “Bad” parts (reference the length of bar graph for results). The degrees of conformity with the pattern achieved with various “Good” and “Bad” parts should be as far apart as possible. The threshold value should be set approximately at the center of this difference between the “Good” and “Bad” parts.


10000000877(02) 35

Detector Types—Detailed Description

The following detector types are available: Pattern Matching, Brightness, and Contrast. The EtherNet/IP model also has a Contour Matching detector type.

Pattern Matching

With this method, the detector looks for a pattern in a defined Region of Interest (ROI). By defining this ROI as larger than the pattern there is some tolerance in positioning of the inspected part. The ROI is the yellow frame on the image and the pattern is defined by the red frame. In run mode, the sensor evaluates the ROI on the current image to see if the pattern is present. The evaluated pattern must match the taught pattern to a degree of conformity greater than the minimum threshold value (and less than the maximum threshold value).

Example: The sensor is taught the following pattern:

In the next row of three patterns, each pattern is recognized with 100% conformity because the evaluated pattern is exactly the same as the taught pattern even though it is in a different position in the Region of Interest (ROI). It differs only in direction X and Y and is not rotated.

In the next row of three patterns, each pattern is recognized but with less than 100% conformity. Pass or Fail result is dependant on the threshold settings (degree of conformity).

Pattern detection is also tolerant of up to ± 5° of rotation. The next two images would be recognized. Due to the slightly rotated orientation of the pattern, the conformity would be less than 100% even though there is 100% pixel conformity. (Patterns with more than 5° of rotation are not recognized.)

Brightness

The MultiSight uses an 8 bit grey-scale CCD chip to capture images. The chip assigns each pixel a value of 0 (black) to 255 (white). The Brightness Detector Type evaluates all pixels that are darker than grey-scale value 128 as black. The detector examines the Region of Interest (ROI) and determines the “Brightness” level (White = 100%, Black = 0%). If this level is between the configured threshold minimum and maximum, the detector passes the evaluation.

The shutter speed has a significant effect on the number of pixels which are evaluated as black and thus which images pass or fail this inspection.

E


36 10000000877(02)

For example, here is the same image with three different shutter speeds:

The setting of the threshold determines the maximum number of pixels detected as being dark which is required to pass the evaluation. The position of each dark pixel within the ROI does not affect the evaluation.

Example:

These two images produce exactly the same result in the brightness evaluation because in each case 9 of the 25 pixels are detected as dark.

Contrast

The Contrast Detector Type evaluates the difference between the brightness levels of the pixels in the ROI. An image that is all one shade of one color has low contrast. An image that is half white and half black has very high contrast.

Example:

Summary of Brightness and Contrast Detector Types

For Contrast and Brightness Detector Types, the teach function is only used for Automatic Shutter Adjustment. It is recommended that the Shutter Adjustment parameter is set to Manual, in which case the Teach command has no effect.

Contour Matching

The Contour Matching detector type is essentially a simplified pattern matching algorithm. Instead of the fully detailed pattern with relative grey scale levels and complex area evaluation used for comparison in the Pattern Matching detector type, the Contour Matching detector type compares simple line contours and shapes. In contour mode, the teach process identifies the borders between dark and bright areas on the image. These borders between dark and light are highlighted with a blue line and subsequently represent what the MultiSight looks for in run mode. When the MultiSight performs an inspection in run mode, it identifies these line shapes and determines if they match the taught line contour. The threshold settings affect how closely the found line shapes match the taught line shape.

As an example, a solid black circle on a white background would cause a single circular contour line. A black ring on a white background would cause a large circular contour line (at the outer diameter) and within it a smaller circular contour line (the inner diameter). There is a contour line tracing border between black and white.

The primary advantage of Contour Matching (in comparison to Pattern Matching) is that this detector type is fully tolerant of shape rotation, i.e. the object may appear in any angular position and still be detected. Another advantage is that the taught contour can be edited by the user to remove parts of the contour that are not to be used for the inspection. The primary disadvantage of Contour Matching (in comparison to Pattern Matching) is that it cannot detect as complex a pattern. Contour Matching is also typically slower.

To edit the taught line contour, place the cursor over the pattern in the Pattern section of the software on the right hand side of the screen. The cursor becomes an eraser. The size of the eraser is determined by the Eraser Size parameter under the pattern. It is recommended to use the Zoom button (in the Pattern section) to work with a larger image. This eraser can be used to eliminate portions of the taught line contour (depicted as a blue line) that should not be included in the inspection. For example, another component near the part to be inspected, or even a shadow, may cause a contour shape in the taught image. The blue contour lines created by these conditions can be eliminated by placing the cursor-eraser over those sections and clicking the mouse button. If a desired blue contour line is accidentally deleted, the entire contour must be re-taught.

There are several additional parameters that appear when the Contour Matching detector type is used. These parameters affect either the teach process or the inspection process. They are described in more detail below. For most applications these can remain in their default states.

For a repeatable inspection results using the Contour Matching detector type, a high-contrast image is essential.

Edge contrast1 Difference in grey-scale value.Minimum difference in grey scale value to define a line contour, i.e. the min. difference between bright and dark areas to get a blue contour line.Defined in terms of 8 bit grey scale valueValue range = 7…128, default = 50.

Edge gradient1 Edge steepness.Maximum number of pixels for the edge width, within which the above edge contrast difference should take place.Value range = 6…19, default = 12.

Min. edge length1 Minimum length of a contour element.For removing or allowing small contour lines.Value range = 4…24, default = 8

Search mode2 Complete search = Searches the entire ROI for the contour with the best match. If multiple matches are found, the best match is identified.Until 1st good = Stops search as soon as first contour match is found. Results in faster application speed but risks matching similar line contours in the ROI.

This parameter gives the user the capability to improve the speed of the application at the expense of accuracy.

Edge width2 Position tolerance.Allows for more or less tolerance in matching a contour to the taught contour. Defined in number of pixels. Used for deviations in shape.Value options = 3, 5, 7, 9, default = 5

Note: The default settings for all Contour Matching parameters can be used for most applications

1 Parameter for teaching

2 Parameter for evaluation

The angle information displayed in the Results area and available via the EtherNet/IP connection is only a rough estimation. To help improve the precision of angle data, the Contour Matching parameters should use the following settings:

Edge contrast: set value as high as possibleEdge gradient: set value as low as possibleMin. edge length: set value as high as possibleSearch mode: Complete SearchEdge width: set value as low as possible


Min. scaling2 Minimum factor for scaling the size of the contour.Values = 0.5 … 1.0, default = 1.0

Max. scaling2 Maximum factor for scaling the size of the contour.Values = 1.0 … 1.5, default = 1.0

Starting angle2 Angle at which the search starts. Search in clockwise direction.Values = -180° … 179°, default = -10°0° = 12:00am on a clock

Total angle2 Maximum search angle. Used to reduce the angular positions that are inspected, so that only a contour with minimal displacement from the original angular position is matched. E.G. – The application is to confirm that a part is in the correct orientation, so reduce the Total angle. If the part is not in the correct orientation, the contour will not be found.

Threshold Contour2 Threshold Contour defines the minimum evaluation score for the inspection to pass. Threshold is adjusted by the slider.Values = 0.00 … 1.00 in increments of 0.05The threshold value is depicted by a small vertical black line on the detector results bar graph when the sensor is in run mode.

Configurable Delays

There are three timing mechanisms that can be used: Trigger Delay, Output Delay, and Output Duration. Each has a range of 0…3000 ms. The following timing diagrams show the behavior of the outputs for each timing mechanism condition.

Case 1: No delay timers used (default state)

Case 2) Trigger Delay = Time (in ms) between the Trigger Input turning on (rising edge) and the image exposure

OUT4(Ready/Busy)

OUT 1+2(Pass/Fail)


10000000877(02) 41

Case 3) Output Delay = Time (in ms) between the Trigger and the availability of results from Output 1+2 (Pass/Fail). Note that the Output Delay must be longer than the evaluation time.

Case 4) Output Duration = Duration (in ms) of the result output on Outputs 1+2. The outputs will turn OFF once the Output Duration is complete (unless the Output Active parameter is set to LOW/Normally Closed, in which case the outputs will turn ON once the Output Duration is complete)

When the configurable delays are used, the minimum total cycle time will be at least as long as the sum of the delay times. This will reduce the number of inspections that can be made in a given period of time.

A new part cannot initiate a trigger signal until the previous evaluation, timing delays, and output duration are complete.

This output shows when the sensor is ready to make an evaluation but DOES NOT show when the results of the previous evaluation are valid.

Turned ON while sensor is waiting for an external trigger. Turned OFF when an evaluation is initiated (either with the external trigger or Trigger Delay after the external trigger). Turned ON again after the evaluation is processed AND the Output Duration has elapsed. OUT1 and OUT2 are reset (outlined below) at the same time as OUT4 is turned ON.

This means that there is no output to confirm OUT1 and OUT2 data validity. The PLC must account for the evaluation time before reading the output results.

Screen Shot Field name Description

Region of Interest (ROI) – Yellow frame with a number

Frames: Region of Interest (ROI - Yellow),Pattern (Red),Position (Blue), and Match (Green)

When a detector is selected (radio buttons in Select Detector window) its ROI appears as a yellow frame with a number on the image. The ROI can be selected by double clicking anywhere inside it. A dot will be displayed just outside each corner and along each side to indicate that it is selected. When the ROI frame is selected, it can be moved by clicking and dragging inside the frame and it can be resized by placing the cursor on the side or corner and then clicking and dragging.

The red pattern frame within the ROI is used to teach the pattern or contour to be detected. When the Teach button is clicked, whatever pattern is in the red frame is taught to the sensor. Double click inside the red frame to select it and then resize or move it.

In run mode, the green match frame indicates where the pattern or contour was detected.

The blue frame is the position frame and only appears when the Position Control parameter is active.

The ROI, pattern, and position frames of non-selected detectors will appear if the Display Icon check box in the Select Detector window is checked. They are greyed out to differentiate them from the currently selected detector.

Live Display Displays the current live image of the MultiSight and continuously refreshes the image.

Zoom Magnifies the image with a digital zoom (2:1 ratio). The ROI and Pattern frames are displayed and can be adjusted.

Save image Saves the current image as a bitmap file (.bmp) with or without the ROI, pattern, and position frames.

Max. Pattern Size Select a maximum pattern size of 400 x 160, 160 x 400, or 248 x 248 pixels.

Screen Shot Field name Description

Display: ROI, Pattern, and Position

For currently non-selected detectors whose Display Icon check box is selected, the check boxes determine whether each respective frame is displayed on the image.

Single Image (via Trigger)

Allows the user to capture a single image initiated by the external (or software) trigger, including trigger delay parameter settings. This allows the user to capture an image for teaching without stopping the production line. This also can be used to identify the ideal trigger delay setting.

Redraw (Brightness detector type only)

When using the brightness detector type, the image will color all of the “dark” (or “light”) pixels blue (or other selected color).

Region of Interest (yellow frame with detector #) should always fully surround the pattern to be detected. It defines the maximum search area in which the pattern will be recognized.

Pattern (red frame)Defines the pattern or contour to be taught. During the inspection process the pattern frame does not have any function other than to mark the original location of the taught pattern. The green match frame indicates where the pattern was detected.

Position frame (blue)The Position Control (OUT2) determines whether the detected pattern’s center is within this frame.


10000000877(02) 45

Recommendations for selecting a pattern or contour:

For reliable evaluation

- The pattern/contour should have a unique characteristic—some aspect that does not occur on a “bad” part.

- Patterns or pattern characteristics should have clear contours/shapes.

- Pattern/contour characteristics should NOT vary.- The pattern area should be set as large as possible within the

image. A pattern that fills 10% of the image will be more reliably detected than a pattern that only fills 1% of the image. If necessary, move the sensor closer to the target.

The pattern area (red frame) should be entirely within the yellow frame (region of interest).

For higher resolution and speed, do not set the yellow frame larger than necessary relative to the size of the pattern. The larger the area that requires evaluation (namely, the ROI) relative to the size of the pattern, the slower the evaluation time.

Position Deviation Check and Frame Type

Position control can be activated when the pattern matching or contour matching detector types are selected. If position control is selected, a blue frame is displayed on image screen. The X/Y coordinates for the center of the pattern detected (green cross at the center of the green frame) with reference to the top left-hand corner of the image (zero point) is displayed in the result window. The increment for X/Y coordinate values while using Detector Type Pattern Matching is 2 pixels so only even coordinate values will occur. The center of the detected green pattern area (green cross) is inside the blue frame for correctly positioned parts. In Run mode, this will activate the position output OUT2.

The center of the detected pattern (indicated by the green cross in the green frame) is within the blue position frame. Position output OUT2 would be active.

Pattern

The Pattern window shows the taught pattern or contour for the currently selected detector.

Save Pattern Saves the taught pattern (or contour) as a bitmap file (.bmp)

Zoom Opens a window showing an enlarged version of the pattern (2:1 ratio, digital zoom)

Eraser size (contour matching only)—determines the size (in pixels) of the square eraser that can be used to edit the taught contour (which is depicted as a blue line). The cursor acts as the eraser when clicked on the contour in the pattern window. Undesired contour lines, such as those caused by other parts or shadows, can be deleted.

Status Line

The Status Line along the bottom right edge of the screen shows the current status of the last action performed.

Field Description

Result Bar Graph The degree of conformity of the current pattern with the pattern taught is shown as a bar graph. The status of the overall inspection is shown as a green (pass) or red (fail) dot. The result is determined by whether the degree of conformity is within the configured thresholds.

For a standalone detector, the bar graph indicates the degree of conformity.

For logically linked detectors, the bar graph represents the detector with the highest degree of conformity (measurement value). The threshold value set in “Detector Parameters” section is shown as a black line.

X/Y Position Shows the X and Y coordinates of the detected pattern (center of green frame) with reference to the zero point (upper left-hand corner of the field of view) and a coordinate system of X = 640 and Y = 480 units.

Direction With “center,” “top,” “top right,” “right,” etc. shows the direction in which the current pattern deviates from the taught pattern with reference to position. “Center” is displayed (or LED = green/OUT2 = high) as long as the center of the green frame (green cross) is located inside the blue position frame.

Counters After every activation of Run mode, the three counters are reset to zero. For the purposes of these counters, an evaluation cycle of five logically linked detectors (resulting in a single output) is counted as one evaluation.

# Evaluations Displays the number of evaluation cycles since the last activation of Run mode.

# Good Patterns Number of evaluation that resulted in OUT1 (pass/fail) output of PASS

# Good Positions Number of evaluation that resulted in OUT2 (position) output of PASS

Sort result (Only when logic is set to OR)Displays which detector had the highest evaluation score

Rotation angle (Only for contour match)Displays the angle of the detected contour with reference to the taught contour position. This data is not highly precise—typical tolerance is ±10°

The Status Line indicates that the software is currently executing a task. It is best to not attempt additional tasks while the Status Bar indicates software activity.

Setup—Quick Guide

Preparation1. Double click the MultiSight software icon to launch the Sensor Finder software.

2. The Sensor Finder software will show ALL MultiSight sensors on the local Ethernet network. Select the sensor and set the IP address if necessary. The IP address and subnet mask of the PC is shown at the bottom of the window.

3. Select the MultiSight by clicking on its IP address. Establish the connection by clicking Connect. A warning will pop up asking if you want to stop run mode. Click Yes. The configuration software will now open.

Optimize Image

4. Click the Live Display button under the Image. The MultiSight illumination LEDs will begin flashing and you will get updated images.

5. Place the target (terminal block or other item for inspection) in the Image area.

6. Notice that the Image is either too bright or dark and out of focus. The first step in a new application is to perfect the image. Two factors affect the image: shutter speed and the manual focus. The shutter parameter is in the Detector Parameters section (third column) about half way down the list. Adjust the shutter speed by clicking on the current shutter speed and typing in a new speed or dragging the slider bar. Make the image darker or brighter by adjusting the shutter speed lower or higher.


50 10000000877(02)

7. Slowly adjust the manual focus on the back of the MultiSight using the small screw driver until the image comes into focus. You may need to adjust the shutter speed more to get the best image. The ideal is to have a high level of contrast and a sharp focus.

8. Click Stop in the Image window to exit live image mode.

Define Search CriteriaThe next step is to position the Region of Interest (ROI) and Pattern frames. The yellow ROI frame defines WHERE the sensor will look for a pattern; the red Pattern frame will define WHAT the sensor will look for.

9. By default, the yellow ROI frame will be selected – notice the dot at each corner and along each side. Double click the red frame to select it. Position and resize the red pattern frame around the unique feature to be inspected (the pattern that will always be there on a good part and never for a bad part).

10. Next adjust the yellow Region of Interest (ROI) frame. This frame defines WHERE the sensor will look for the pattern we defined with the red box. This means it must always be bigger than and completely containing the red frame. Double click the yellow frame to select it. Move and resize the frame.


10000000877(02) 51

11. In the Detector Parameters section (third column), change the Trigger Mode setting to Continuous (from Triggered). While in run mode, this will cause a new inspection to start as soon as the last one finishes. In the Select Detector section (second column), click the Live Images checkbox so that images will be displayed in the software while the sensor is connected.

12. Click the Teach button in the Commands section. Click Teach From PC Image. Once the teach process is complete, the taught pattern appears in the Pattern window on the right.

Function Test

13. Click the Run button in the Commands section. Confirm that the inspection is passing by referencing the indicators. Based on the results of several good and bad parts, you may need to adjust the threshold settings.


52 10000000877(02)

14. Based on the results of several good and bad parts, you may need to adjust the threshold settings. Click the Stop button in the Commands section to return to configuration mode and make adjustments.

Example ApplicationExample: Detecting whether hex nuts are welded on mounting brackets by using the detector type “Pattern Matching.”

During machine assembly, inspect mounting brackets to ensure that hex nuts are welded in specified places.

Condition:

Mount the MultiSight sensor in position (see “Installation” on page 6) and attach all cables and wires per “Electrical Installation” on page 8 and “Connector Pin Assignments” on page 66. The software connection to the MultiSight is described in the “Start-up” section on page 18.


10000000877(02) 53

When the MultiSight is powered up, the image shown in the “Image” section of the computer software is the last image recorded. For setting up a new inspection, click on the “Reset” Command button. To view and continuously update the live image, click the “Live Image” button.

To bring the object into focus, turn the focusing screw on the back of the sensor.

To improve the contrast, use the “Shutter” in “Detector Parameters.”

Set up:

Select Detector Type to be “Pattern Match” in the “Detector Parameters” section.

Set region of interest (ROI) by double clicking on the yellow box and placing it on the image. This is the area in which the MultiSight will look for the taught pattern.

Set pattern by double clicking on the red frame and placing it on the image where the inspection needs to be performed.

In most cases, the majority of the parameters can be set using the standard settings. A different setting may be necessary to improve detection or shorten cycle times.

IMPORTANT


54 10000000877(02)

Click on the “Stop” button to stop live image.

Change the trigger mode to “Continuous.”

This makes it easier to check good and bad parts.

Click on the “Teach” and select “Teach from PC image” button to teach the pattern. Click on the “Stop” button after a few seconds.

Notice the taught pattern display in the “Pattern Section.”

Select “Live Images” check box in the Select Detector section. Click the “Run” button. The pattern is now evaluated continuously.

The desired pattern is detected with 100% conformity.

The green outline on the image indicates where the taught pattern is found. The green bar graph (in the “Results” & “Select Detector” windows) indicates the degree of similarity to the taught pattern. The black line on the bar graph is the current threshold.

Further objects can be set using the same procedure described above. Select a new detector in “Select Detector” section, select the desired parameters in “Detector Parameter” section and repeat the above steps.

If several objects or detectors are defined, they can be logically linked or grouped (see Select Detector/Logic on page 26).

Set the threshold value (required degree of conformity of the pattern detected with the pattern taught). This can be achieved by testing a variety of good parts and adjusting the “Threshold Min” parameter in the “Detector Parameters” window.

Appendix

Frequently Asked QuestionsHow do I change the IP address of the MultiSight sensor?

Proceed as described in “Network Settings” and “Setting the IP Address of the MultiSight Sensor” sections on pages 11 and 15, respectively.

What is the easiest way of testing the connection to the MultiSight?In the start menu of the operating system, click on “Run” and then “cmd.” In the window which appears, enter the command “Ping” and then the MultiSight IP address:e.g., ping 192.168.100.100

If all connections are correct, and the sensor and the PC address section are identical and the MultiSight is ready for operation, the command “Ping” will produce a positive signal. If not, re-check your network configurations and consult your network administrator.

How do I avoid image dissipation and reflections (indicated by light-colored areas of the image)?Mount the MultiSight and set the shutter manually. Adjust the illumination of the object and avoid fluctuations in brightness, e.g. due to ambient light.

I am getting dissipation of image and brightness for the same object. The brightness values at the edge of the illuminated image zone differ from image to image. What can I do?Set the shutter to “Manual” in the window “Detector Parameters” and set the slide so that there is no fluctuation in brightness. Generally speaking, a higher shutter value causes slight overexposure, but also produces a more consistent result.

Reflections occur when the alignment or position are changed slightly, e.g., an impression which varies in brightness. How can I get a more consistent image?Mount the MultiSight at an angle of 10…15° so that it is at a slight angle to the reflecting surface (see the illustration on page 7). Or select another position for the pattern screen in which the reflections do not adversely affect pattern detection (see “Installation” on page 6).

1. Rising edge at IN1 (Trigger) starts sensor (triggers exposure and processing).

2. Trigger starts falling edge at OUT4 (Ready). Ready stays low for duration of evaluation. (Duration of evaluation is indicated in Run mode with Trigger mode = “Continuous” in sax ms at the bottom right hand of the software screen.)

3. The rising edge at OUT4 (Ready) indicates (1) that processing is complete and (2) that the outputs OUT1 (= result of evaluation) and OUT2 (position) are now valid (A) and can be processed by the control system (unless output duration 0, see Configurable Delays section on page 40).

4. The next rising edge at the trigger input IN1 starts the next evaluation.

5. Period between rising edge at output OUT4 (Ready) and next rising edge at trigger input (IN1) = period which can be used for changing from detector to detector (activate 0 or 1; activate 0 to 31) or Teach temporary/permanently by control input IN2.

Case 1: Control Input = Enable

Control input = Enable means that IN2 must be connected to V+ (+24 V DC) to allow the external trigger.

Case 2: Control input = Activate 0 or 1

This function allows the Control Input to determine whether detector 1 or detector 2 is evaluated. A change in the state of the control input (B) can take place in period “5” (Ready = high). A high level (V+) on the control input IN2 means evaluation according to detector 2 configuration, a low level (V-/GND) means evaluation according to detector 1 configuration (more details below).

Case 3: Control input = Activate 0 to 31

This function allows the Control Input to determine which detector is evaluated by using a series of pulses during the Ready state. In period “5” (Ready = high/V+) pulses are counted “C” (type: 5 ms pause/5 ms pulse/5 ms pause/etc.). The next evaluation takes place with the detector corresponding to the number of pulses counted. The count always starts at 1, regardless of which detector was active previously. The pulses must be generated bounce-free, preferably by a control system (more details below).

Case 4: Control input = Teach temporary or Teach permanently (only possible on detector 1)

This function allows the MultiSight to be taught a new pattern without being connected to the software. In period “5” (Ready = high/V+), a high level (V+) can be applied at IN2 to trigger a temporary (saved in RAM only) or permanent Teach (saved in flash). This must be applied at least until the next rising edge at trigger input IN1. Then the new pattern is taught in detector 1 and saved according to specification. The control input IN2 must be pulled low (V-/GND) before the next rising edge at trigger input IN1, or another Teach is triggered. In this mode, only detector 1 is used and overwritten by the next Teach. Detector 1 can still be logically linked to other detectors (more details below).

The parameter Control Input can be set up to allow the control input IN2 to select between the different detectors. The parameter setting is Activate 0 or 1 OR Activate 0 to 31.

If control input = enable (default state), IN2 (grey wire) MUST be connected to V+ (24V DC) for the external trigger to work.

When one of these options is selected, the following parameters must be set accordingly for all used detectors:

Control Input must be the same for all (either “Activate 0 or 1 OR Activate 0 to 31”) (more details below)

Shutter Adjustment = Manual

Trigger mode = Triggered

It is recommended to keep a list of which pattern is saved in which detector number.

When changing detectors, if a detector is selected that does not have the Control Input parameter set to Activate 0 to 31 (or Activate 0 or 1), it is not possible to change to another detector using the control input IN2. The control input has a different function and therefore is no longer capable of switching to another detector. For this reason, it must be confirmed that the control system only selects detectors that are configured to allow the control input to change detectors. If an incorrectly configured detector is selected, the sensor may no longer respond and therefore would need to be reconfigured by connecting to the software.

Recommended Procedure:Configure detector 1 with the desired parameters, including the above required parameters (Control Input = Activate 0 to 31, Shutter Adjustment = Manual, Trigger Mode = Triggered).

Use the Copy command to copy the required parameters from Detector 1 to the other detectors required for use (instructions on pages 25 and 29).

Set up the control system to generate the appropriate number of pulses for detector selection during the OUT4 Ready signal.

Testing Saved Detectors:When all detectors to be used have been configured as described above, a detector can be selected using the radio buttons in the Select Detector window. Put the sensor into Run mode (Run command). The sensor starts with the last detector selected (via the radio buttons or the control input IN2). The detector can now be tested using various “good” or “bad” parts. Parameters such as Shutter or Threshold value can be adjusted if required. To test other detectors, select the radio button of that detector.

Control Input: Teach Temporary or Teach Permanent (Case 4)

The parameter Control Input can be set up to allow the control input IN2 to allow a pattern Teach for the first detector. This gives the input on the PWR and I/O connector the same functionality as the Teach command button so that the software does not have to be connected for a Teach function to occur. (Only for the first detector.) The Teach function occurs when the external trigger (IN1) transitions low (GND) to high (V+/24V DC) while the control input IN2 is high (V+/24V DC). The signal sequence is as follows:

High level (V+/24V DC) on control input IN2

Rising edge (GND to V+) to trigger input IN1

Note that if a second trigger on IN1 occurs while the control input IN2 is held high (V+) a second Teach function will occur. Be sure that the control input IN2 is pulled low (GND) after the Teach function is completed.

Applications where the object is continuously moving:

Pull control input IN2 high (V+) for at least one external trigger/image exposure. The new pattern for detector 1 is saved and this new configuration applies immediately. If the signal at input IN2 is held high (V+) for several trigger cycles (several image exposures), the last exposure is saved as the new pattern for the first detector.

Applications with Timer Delays:Apply a High level (V+/24V DC) to control input IN2 when the next target object is being transported to the evaluation position, therefore causing a trigger signal,

OR

when the reference object is in the correct position and triggering has already taken place (due to a Trigger Delay), the trigger signal must be interrupted and re-triggered (the teach is initiated by the rising edge of the trigger input IN1). Only after this should the signal at control input IN2 fall to low level (GND). Interruption and re-application of the trigger signal can be achieved by installing a control relay in the trigger circuit or by using a PLC to drive the trigger (as opposed to directly wiring from a trigger sensor).


62 10000000877(02)

The save operation for permanent save (Teach permanent) may take up to 500 ms.

During this period in continuous moving applications, the output locks to FAIL regardless of the part evaluation (i.e. both “good” and “bad” parts give a FAIL output). When the Teach Temporary function is used, the new pattern is stored only in the RAM (this requires much less time). In this case, the pattern is no longer available after the MultiSight is reset and must therefore be re-taught.

Trigger Mode Parameter

Triggered or Continuous

When “Triggered” is selected, the sensor initiates an exposure and evaluation when the external trigger IN1 transitions from low (GND) to high (V+/24V DC) or the “Trigger” command button in the computer software is clicked.

When the “Continuous” Trigger Mode is selected, the sensor initiates a new exposure and evaluation as soon as the last evaluation is complete, i.e., the sensor cycles as fast as possible. This Continuous internal triggering is initiated as soon as the sensor is put in Run mode.

Setting Up the Trigger Sensor

During operation of the MultiSight sensor, the position of the additional external trigger sensor can be optimized. To do this, make the following parameter settings to the PC software:

• Trigger mode = “Triggered”• “Live Images” in Run mode = check box selected (live images update activated)• Click the Run command button to put the sensor in Run mode

Observe the exposure that is continuously updating in the Image window. Note where the pattern to be inspected falls within the Field of View. Adjust the position of the trigger sensor to optimize its position in relation to the exposure Field of View.

Minimum Operating Distance and Field of View by Cat. No.

An operating distance of more than 100 mm may require external lighting.

The typical focus range is operating distance ± 5%.

The 48MS-SE1PF1-M2 and 48MS-SN1PF1-M2 (6 mm focal length models) typically require external lighting because the integrated lighting does not illuminate the entire field of view, i.e., the edges of image are dark.
